Motherboard Battery

Why do you think a battery replacement would help? What errors / symptoms are you experiencing?

I had a look at the manual (via Asus click here), but there is no instructions on how to open the case to access/replace the CMOS battery. I think you'll need a 'service manual' for this but I couldn't find one.

It would freeze now and again and saw a post where someone had same problem. They checked battery and found it was not working properly and change it and it worked. Different laptop. Tried different solutions for freezing. When I installed more memory it seemed to help but not fully.
